A drug form (such as blotter or liquid) thought to be or contain solely LSD.

Slang for other LSD-like drugs (incorrect use). The term "acid" has been used as a common name for d-LSD since at least 1965. Although confusion associated with research chemicals / new psychoactive substances has lead some people to use the term 'acid' to refer to anything LSD-like or anything psychedelic on blotter or sold in drops, we believe this represents an error and not a useful evolution in language. Acknowledging the complexity of possible pro-drug relationships like p-LSD, it is still inappropriate to call anything other than LSD "acid" without further qualification ("p-LSD acid", or "LSZ Acid").

In reference to drugs, a pattern of consumption marked by compulsive taking of a drug, the need for increased doses over time to maintain the same effect (tolerance), and the appearance of symptons when the drug is stopped that disappear when it is reinstituted (withdrawal).

Neologism. Erowid. Coined 2017. Inability to remember the name for a person, place, animal, or thing. Possibly a subtype of amnemonologia. More socially disabling than amnemonologia, because it is insulting to friends to not remember their names.

An alkaloid found in many plants of the nightshade family that blocks nerve impulses in the parasypathetic nervous system. It is used in medicines as an antidote for nerve gas poisoning, as a treatment for gastrointestinal spasm, and as a presurgical drug to dry secretions in the respiratory tract.

1. A presynaptic receptor acted upon by the transmitter released at the same nerve ending. Autoreceptors are receptor structures on nerve/brain cells which are activated by the transmitter chemical that its own cell body releases. Standard receptors are activated by transmitters released by other, nearby cells. 5-HT-1a is an example of an autoreceptor.

a biological compartment is any portion of the body separated by an equilibrium gradient barrier/impedement, such as a cell membrane, though contiguoous regions of tissue, viz. organs, are generally considered a single compartment for pharmacokinetic concerns. Note that in this regard, blood/plasma is considered its own compartment.

A consumption method for psychoactives and medicines, often mis-named "chewing", where the material is held in the side of the mouth to absorb the active ingredients. Used for such things as tobacco, betel nut, khat, etc.

Theobroma cacao, a tropical tree, source of cacao beans. the beans contain a high proportaion of fat, called cocoa butter. If the beans are heated, ground to a paste, and enriched with additional cocoa butter, the product is chocolate. Ground, defatted beans make cocoa. White chocolate is cocoa butter mixed with sugar.

A simple pipe made in a tube or funnel shape, often of clay, but sometimes of metal or wood. Most commonly associated with cannabis smoking, but can be and is used for smoking anything. Perhaps the simplest of pipes, the general concept is that the hands act as one chamber of the pipe and the mouth is placed against the hands and when the smoker breathes in, the air is pulled through the chillum.

Smoking material is placed in one end (the larger or bowl-shaped end). In the single-handed style, a hollow fist is made with one hand with the finger tips all touching the palm tightly and the narrower end of the chillum is placed between the second and third fingers. The mouth is placed against the thumb-side opening in the hollow fist. The material is lit and the smoker inhales through the hand-chamber and adjusts the fingers so that suction is created through the pipe. One benefit of this style of pipe smoking is that it is fairly easy to regulat the air/smoke mixture to cool the incoming smoke.

Using two hands cupped together to form the pipe chamber is common and there are many variants of how to hold the hands. A variant of this can be seen in the Cannabis Vault.

Chillum smoking is quite common in southern Asia (India and nearby countries). It is well known in subcultures in the Americas and Europe.

"Chillum-style" joint smoking: Using a cannabis cigarette or joint as the pipe and placing the unlit end between the fingers is sometimes called "chillum-style" joint smoking. It both allows for more cooling of the smoke as well as avoiding contact with the saliva of others when sharing joints in groups. This style is sometimes used when people with colds or flus are asked not to put their lips on shared pipes or joints and also allows for "shotgunning" a joint.

the part of the nervous system comprising the brain, the brain stem, and spinal cord. It is to this system that ll senses connect (the afferent pathways) and it is from this system that all motor commands emanate (the efferent pathways)

Preparation of a medicinal plant made by boiling the material in water, as opposed to an infusion, in which the substance is merely steeped. Infusions are appropriate for leaves and flowers. Woods, barks, and roots are often prepared as decoctions.

A sleep experience characterized by falling in and out of consciousness many times, floating between fully awake, hypnogogic states, and unconsciousness. Disco-napping usually occurs after taking a long acting psychedelic (e.g. LSD), stimulant, or while trying to sleep in very noisy, chaotic conditions. After LSD or similar, the disco-napping often includes a nervous-system restlessness.

A war between the need to sleep and a variety of small discomforts and shades of large stimulants.

the term was originally coined by Dave Nichols (co-founder of the Heffter Institute) to refer to substances which generate a sense of "the touch within". Entactogen is used interchangeably with empathogen, by some. However, the literal derivation of the word --to create or causes a change in the sense of touch--has also led to the word being used to describe substances which affect an individual's physical sensations of touch.

psychoactive sacrament; a plant or chemical substance taken to occasion spiritual or mystical experience

hallucinogen; psychedelic

any practice or substance leading to poetic or prophetic inspiration

See The Road to Eleusis and The Age of Entheogens & The Angels' Dictionary. The term was coined in 1978 by a group of academics lead by R. G. Wasson and Carl A.P. Ruck and including Jonathan Ott, Danny Staples, and Jeremy Bigwood. Although "theo" is Greek for both "spirit" and "god/God", the term "entheos" saw use
in Greek literature meaning inspired poetically or prophetically.

en = in / withintheo = spirit, Godgen = create, generate

Ott describes the neologizing in "Angels' Dictionary" : "We finally settled on the neologism entheogenic, from the Greek entheos, a term used in the classical world to describe prophetic or poetic inspiration. The term means literally 'becoming divine within', and can be seen as the user realizing that the divine infuses all of the creation, or specifically that the entheogenic plant is itself infused with the divine. It is not a theological term, makes no reference to any deity, and is not meant to be a pharmacological term for designating a specific chemical class of drugs (psychedelic, for example,has come to be seen by some sensu strictu as a term to designate mescaline-like B-phenethylamines or DMT-like tryptamines). Rather, it is a cultural term to include all of the shamanic inebriants - sacraments, plant teachers, the stock-in-trade of shamans the world over."

A medical practitioner who follows the precepts of Samuel Hahnemann (1755-1843), the German physician who invented homeopathy. Homeopaths believe that people get sick in unique ways and that they can be cured by administering minute doses of substances that, given in large doses to healthy persons, would reproduce the unique pattern of symptons. Homeopathy was very strong in Europe and America in the mid-nineteenth century, declined with the rise of technological medicine, and now is having a modest resurgence.

An abnormal separation of the conscious, observing mind from other areas of mental function, often occurring under sever stress. In dissociative states, people may perform complicated actions automatically and unconsciously, being oblivious to pain or injury they may have suffered.

A person of either sex who drives a car, motorcycle, or even a bicycle, for that matter, on a public road while under the influence of a psychedelic drug. Most researchers in this area have done it at least once, sometimes in an emergency, but only in a life-and-death situation is it excusable.

A route of administration where a powder or liquid substance is introduced into the sinuses by lightly inhaling the material through the nose without pulling it into the lungs or trachea.

In anthropological texts, insufflate is often used to refer to blowing a substance up another person's nose using a tube or reed. Blowing powders up another's nose is essentially unheard of outside traditional ceremonies.

A part of the evolutionarily old brain containing centers of pain and pleasure; also associated with memory and emotion. It is possible that this area of the brain is involved in altered states of consciousness, highs, and responses to psychoactive drugs.

Any of several large desert plants of the New World, of the genus Agave in the lily family. Varieties of century plants, they have thick, swordlike leaves that develop from a central cone. the sap of magueys is the basi of several native Mexican alcoholic beverages, including pulque, mezcal, an0d tequila.

The ability to understand, remember, and act appropriately based on medical and scientific information so that actions, drugs taken/avoided, foods eaten/avoided, doses used, etc result in beneficial outcomes.

A synthetic, long-acting narcotic, used in treatment programs to maintain heroin addicts. Taken orally, it gives little euphoria and blocks the effect of heroin. Withdrawal from methadone can be more difficult than withdrawal from heroin.

A drug derived from opium or chemically related to the compouds in opium. narcotics depress central nervous system functioning and, in chronic use, can produce a dependence syndrome marked by tolerance and withdrawal.

Any plant belonging to the Solanaceae (nightshade or potato) family. Tomatoes, potatoes, eggplants, and chilies are members of this group, along with a number of more dangerous plants, such as tobacco and Datura.

A peripheral response to a drug which can be felt as tingling, pins-and-needles, or hair standing on end; it might take the form of a chill (even if the air is warm), or a feeling that one's skin is crawling.

that branch of the autonomic nervous system that tends to slow down body functions and promote relaxation. Nerves of this system leave the head and lower part of the spine and connect to numerous organs, blood vessels, and glands.

A small, spineless cactus, Lophophora williamsii, native to north-central Mexico and adjacent areas of Texas and New Mexico. Peyote contains several dozen alkaloids, of which mescaline is the best known. Many North American Indians injest peyote ceremonially for its psychoactive effect.

A light or pattern which appears in the field of vision with eyes closed (and occasionally open). Phosphenes seem to come from the back of the eyelids, but are actually a result of slight but harmless abnormalities in retinal and visual processing networks.

Any effect on mood, mind, or behavior that is identifiable by an individual or detectable by others.

Psychoactive effects can be secondary to other causes, so a mood or mental change can be caused by a drug or cause not normally considerd psychoactive. An anti-nausea drug might cause a secondary psychoactive effect by reducing or blocking nausea that would otherwise cause dysphoria.

Psychoactive effects are generally considered to be caused centrally, meaning in the brain.

A substance, such as LSD, mescaline, or psilocybin, that, under appropriate conditions of set and setting, can elicit high states marked by philosophic insights, mystical feelings, visions, and so forth. the term reflects a positive bias toward these drugs, which others have called "hallucinogens" (hallucination inducers), "psychotomimetics" (psychosis mimickers), or "entheogens".

Loss of ability to distinguish reality, as perceived by others, from one's own private mental productions. A serious category of mental illness, often marked by hallucinations, delusions, and disturbances of thought and mood.

A physical and mental feeling of accelaration and stimulation most often experienced at the onset of a drug's effects. Can be experienced as waves of pleasure or waves of anxiety; the rush of each substance is unique, although classes of substances share similarities. Some psychoactive users seek drugs that cause strong rushing, others avoid it. Smoking or injecting drugs tends to increase the rush and this is often cited as a reason to smoke orinject.

Adjusting the dosage of a drug oneself to achieve a given effect. Cigarette smokers quickly become adept at self-titrating nicotine levels to maintain a particular level of nicotine in the blood and brain

A priest or medicine man who mediates personally between the human world and spirit world and often attempts to control the forces of good and evil within a tribal community. Shamanism is common among native peoples of northern Asia and North and South America . It frequently involves the use of psychoactive plants to induce altered states of consciousness conducive to magical operations.

A stereoisomer of a given chemical or molecule that has the same
atom-to-atom connections as the molecule in question, but has a shape that is nonsuperimposable with it.
Stereoisomers can be configurational or conformational stereoisomers, and they may be diastereomers or enantiomers.
Human hands are the classic teaching example: both have the same configuration, but are mirror imaged versions of each
other.

Stereoisomerism is the arrangement of atoms in molecules whose connectivity remains the same but their arrangement in space is different in each isomer. Geometric isomerism is sometimes considered synonymous with stereoisomerism, but is often used to describe just those stereoisomers that are not mirror-images of each other.
their are two forms of stereoisomerism: Geometric isomerism aka diastereomerism, Optical isomerism aka enantiomerism. From: Wikipedia

Stereoisomers require a "stereo center" around which the parts of the molecule are rotated to form the different
isomers. these are usually carbon atoms.

Stereoisomers are isomers that have their atoms bonded in the same order: that is, their two dimensional structure can be drawn identically,
yet the atoms differ in their three dimensional positions in space.

Any substance that increases activity in the nervous system. Central nervous system stimulants cause wakefulness, alertness, and feelings of well-being. In overdose they may cause anxiety, jitteriness, and insomnia.

the branch of the autonomic nervous system that mobilizes the body for fight or flight by speeding up the heartbeat and breathing while shutting down digestive functions. Nerves of this system leave the middle segments of the spinal cord to connect to many organs, blood vessels, and glands.

Follower of the philosophy of Taoism, an ancient Chinese system founded by Lao Tzu and outlined in his brief text, the Tao Teh Ching (Way of Life). Taoism stresses the complementary interaction of opposite forces (yin and yang).

In pharmacology, the decrease or loss of response to a drug, due to recent or prolonged exposure to it.

the need for increasing doses of a drug over time to maintain the same effect. Tolerance is a common characteristic of dependence on drugs. It is provoked by some drugs more than others, especially by stimulants and depressants of the central nervous system.
